Which of the following expressions have a value of –√3?

Question

sin(11π/6)
cos(5π/3)
cot(7π/6)
tan(11π/6)
cot(2π/3)
sin(5π/3)
csc(5π/3)
cos(7π/6)
cos(π/6)
csc(2π/3)

I think none..but that is not an option...so do I go with cot(7π/6)

thanks

Answer 1

I already gave you the reference angles of π/6 and π/3
Place them in the various quadrants.

I also told you that 7π/6 is not one of the options, since c0t(x) is positive in QIII

Answer 2

Oobleck...is the answer none then?
Nothing worked
